A novel porous adhesion material with ink absorbency for digital inkjet printing

A novel porous adhesion material for digital inkjet printing with absorbency for eco-solvent ink and removable adhesion has been successfully prepared by a simple, robust and cost-effective method. There was no traditional emulsifier with low molecular weight adopted in the poly(n-butyl acrylates) emulsion for the preparation of the porous material. Due to the properties of this reactive emulsifier, there was no free emulsifier left after the polymerization, thereby reducing the drawbacks associated with traditional emulsifiers. The porous material possesses high shear strength, moderate peel strength and low tack properties suitable for adhesion and could be removable many times, which offered a new method for recycling. Since the novel porous material can be utilized many times and have potential for recycling, we believe that this material would be environmentally friendly. Additionally, the absorbency of the eco-solvent ink created a suitable platform for digital inkjet printing based on the novel porous material, with resistance to different atmospheres, like acid, base, oxidant, and many organic solvents.
